The National Children’s Study is seeking pregnant women and families planning to have children in Hawaiʻi to participate in a long-term study to look at how children’s health is affected by a number of factors.

Feral cats have inhabited Hawaiian forests since soon after their introduction in the late 1700s, contributing to the decline and extinction of native birds. Effective control strategies require data on population dynamics, but little is known about the cats’ annual or lifetime survival rates.
